Distinguishing Coherent Crosstalk from Calibration Drift via Pauli-Transfer Signatures and Quantum Edge Detection
Syed Emad Uddin Shubha, Tasnuva Farheen
Multi-tenant quantum processors expose a pulse-level attack surface in which coherent crosstalk can mimic benign calibration drift at matched average gate infidelity. We present a…
Secure and Efficient n-Qubit Entangled State Teleportation Using Partially Entangled GHZ Channels and Optimal POVM
Animesh Banik, Md. Shihab Khan, Rafid Masrur Khan +2
We introduce an efficient and versatile quantum teleportation protocol for specific types of n-qubit entangled states. By employing a partially entangled Greenberger-Horne-Zeilinge…
Generalized State Discrimination for Tunable Quantum Key Distribution
Animesh Banik, Md. Shihab Khan, Rafid Masrur Khan +2
We introduce a tunable framework for generalized quantum state discrimination (GSD) and apply it to quantum key distribution (QKD) through a protocol we call phiQKD. Building upon…
